It is strongly recommended (by all UV manufacturers) for maximum efficiency of your UV Sterilization, that you pre-filter your water with a 5 Micron sediment cartridge.

Do not connect plastic pipe or tubing directly to the UV system because the UV light will break down plastic over time. The best way to make the connection is with Dielectric Unions that allow for a connection from stainless steel to copper, that will not corrode.

Pre-Filter Required
The most suitable replacement for this is the
Sterilight S5Q-PA

UV Max Systems Warranty:

  • 5-Year Warranty against manufacturer's defects on the power supply and all electrical components
  • 10-Year Guarantee on the Stainless Steel UV Reactor
  • 1-Year Warranty on lamps

How does Ultraviolet Sterilization Work?

The germicidal energy of ultraviolet light destroys harmful microorganisms by attacking their genetic core (DNA). This powerful dose of UV light eliminates their ability to reproduce, and the organisms simply die.

Water is purified by running it through a watertight chamber that contains an ultraviolet lamp. As water flows past, microorganisms are exposed to a lethal dose of germicidal UV energy.

Purification with the UV Max is a safe, natural process that adds no chemicals and does not affect the taste or odor of your water.

Specialized, high output UV lamps maximize the output of germicidal UV energy.
